Switching Counter – Auto Mode
On every rising edge of the input signal, the counter value
is increased (see Fig. 6-4).
If the counter value is less than the configured counter
limit, the counter state flag not reached is set. As soon as
the count value is greater than or equal to the configured
counter limit, the counter state flag reached is set. If the
count value is greater than the configured counter limit, the
count value is automatically reset (count value = one).
The count value can be reset at any time by a system
command (count value = zero).
